These socks are the best. I use them as "oversocks" over a thin pair of nylon socks. They help fill out the wiggle room in my size 14 hiking boots. They're comfortable and they don't itch and they wear like iron. No holes or tears or frayed threads after several washings. Actually, this is my second pair. I bought the new pair because the first pair is so great. A good investment.
I purchased the Capilene 1 for the express purpose of using them as pajama bottoms in my sleeping bag when backpacking. I used to sleep in sweat pants which were too heavy and which made me ah...sweat. The capilene 1 bottoms are light and warm, but not too hot. A perfect solution for me.
I bought the short Therm-a-rest Toughskin. I have used it twice and have been completly satisfied. Not only is it comfortable to sleep on, but I can lean it up against a tree and use it as a seat cushon without worrying about puncture holes. With a few quick breaths, the pad is firm. I actually let out a little air to make it a little softer. I'm 6'2" and the short version is plenty long for my torso. When I turn on my side, my knees fit nicely on the pad. I was a little concerned about paying so much for a pad, but you get what you pay for. It's worth it.
